Ratifications of the Constitution of the United States

The Constitution of the United States became established when New Hampshire became the ninth of the thirteen states to ratify it. Two states, North Carolina and Rhode Island, ratified after the new government had begun operating under the Constitution and twelve amendments, ten of which now make up the Bill of Rights, had been submitted by the Congress to the states for ratification. Additionally, a Constitutional Convention in Vermont, which at the time was a sovereign state, voted to ratify the Constitution and to apply for admission into the Union.
